Author Topic: B1250 top speed (Read 6167 times)

Any guesses (or real experience!) on what the max speed is on the new 1250? I haven't seen this published anywhere.

Also, do you think that top speed would be in 6th, or 5th?

I happen to have a real good idea of what the 6th gear top speed is, haven't tried 5th yet. But I'm not telling yet, I want to hear what others have to say first.

First of all the Bandit 1250 is supposed to have a very optimistic speedo

That said check out this link and click on the new Bandit, then 1250 videos and look at high speed run. I think his speedo hit 170 or 171 on this run.

Now THAT was an interesting clip! No way would I guess this bike's capable of 171, and I'm sure the Holeshot products are good, but can they be THAT good?

I've had mine up to 150 MPH, and that was under reasonably ideal conditions. It was like pulling teeth to get those last few MPH's out of her. However, mine's bone stock and I stayed in 6th.

Looking at that clip, he was redlined on the tach, so I'm thinking that run might have been done in 4th! at 150 MPH in 6th I was only a bit over 7K RPM.

Dave, chime in! Tell us how that speed run was done!

I can tell you this...I won't be trying to find out what top speed is on mine when I get it. Doubt it will ever see 100. I think I've had my FZ1 to maybe 6000 rpm and maybe 90?

I don't need all that drama to have a good time anymore.

I guess at the tender young age of 48, I still have some wild oats to kill off. I still get a thrill out of the occasional high speed run. I can't imagine owning a bike like this and not pushing it up to a buck and a half once in a while.

Now before the safety take-it-to-the-track crowd flames me, I only will attempt such runs under nearly ideal conditions, and I understand completely how dangerous this is (Stopping distance = 3 footballl fields @ 150!

). But ... DAYUM it's fun!

I think Dale might have a 17T front sprocket on that bike which would throw off the speedo even more. I noticed he had no problem getting to redline which leads me to believe it has the 17T front. The Bandit 1250 speedo is off 6 mph according to my very accurate GPS unit

Actually it is off the same as my GSXR1000 to the mph, hmmm think they are trying to get away with something. My V-Stroms were all off closer to 8 mph. If you cange the gearing on this bike the speedo will be further off due to the pickup being at the front sprocket. Me i'm not too concerned about top speed on this bike I have a GSXR1000 to go do that on.

The B1250 is plenty quick but looking at the flat torque curve it was not designed for top speed runs. Torque is what this big boy is made for.

Motorcycle Consumer News measured the bike's top speed at 151.7 mph. August '07 issue.

I keep reading this, but where are you all getting that? I'm 99% sure the speed sensor is on the front wheel, not on the counter-shaft sprocket. I know it was on my SV anyway, is it different on the Bandits?

Starting in 2000 on the B6 and 2001 on the B12, the speedo reads off the countershaft sprocket. (Prior to that, Bandits have cable driven speedos off the front wheel.) I'm guessing this continued with the new 650/1250 since this is the way Suzuki does it on the GSXR's & Hayabusa. I don't know why they chose to do the SV differently.

Well, good to know... learn something everyday.

Look on the C/S sprocket cover and if you see a small wire bundle running down and stopping on a little sensor over where the C/S sprocket is, you've just found the sensor.

I'll keep my eye out for it this weekend when I'm installing my TFI box. Glad I know it's there so I can be careful with it.. the sprocket cover on the SV is just a hunk of metal w/ the clutch cable running into it.. no wires or anything for me to break. When it gets time to change out sprockets, I may have tried to gorilla it off..

Ok, threadjack off, thanks Red.

Dale shot that run with a radar gun and I believe said 161mph. IIRC it was a 5th gear run as well with stock gearing a slip on and some f/i work. Something like 120hp.

That makes sense. That extra 20 HP would account for 10 MPH more, and I suppose 5th gear would approach redline.

I'm truly impressed that the slip-on and re-map gains 20 HP! I may have to give this some serious thought!

I think Dale's dyno run showed an increase from roughly 105 HP stock to 115 HP with kit (slip-on, air filter, & FI box). I assume that's the setup he ran the video with.

Still pretty good, roughly 10% without any significant engine changes, with an increase in torque across the board as well, IIRC.

Still faster than I want to go, but I did have the little stock 600 up to 215 km/hr on the clock (so closer to 190-195 kpmh) across the bare, open Oregon desert earlier this year. That's in the range of 120 mph.
